xdr_vector()--Translate between Arrays and Their XDR

 #include <rpc/xdr.h>

 bool_t xdr_vector(XDR *xdrs,
                   char *arrp,
                   const u_int size,
                   const u_int elsize,
                   const xdrproc_t elproc);

The xdr_vector() function is a filter primitive that translates between fixed-length arrays and their corresponding external representations.

Parameters

xdrs  (Input) 

A pointer to the eXternal Data Representation (XDR) stream handle.

arrp  (I/O) 

The pointer to the array.

size  (Input) 

The element count of the array.

elsize  (Input) 

The byte size of each of the array elements.

elproc  (Input) 

Translates between the C form of the array elements and their external representations. This parameter is an XDR filter.

The following example shows how xdr_vector() is used:

#include <stdio.h>
#include <xdr.h>

#define MAX_VERTECIES 10
#define MAX_EDGES ((MAX_VERTECIES*(MAX_VERTECIES-1))/2)

typedef struct graph
{
        bool_t adjacent[MAX_VERTICIES,MAX_VERTICIES];
} graph ;

bool_t xdr_graph(XDR *xdrs, graph *p_graph)
{
        int i;
        for(i=0;i<MAX_VERTECIES;i++)
                if(!xdr_vector(xdrs,
                p_graph->adjacent[i]
                        AX_VERTECIES,sizeof(bool_t),xdr_bool))
                                return FALSE;
        return TRUE;
